RADIATOR.

Specification of Letters Patent.

Patented J an. 17, 1922.

Application filed July 21, 1920. Serial No. 397,906.

To all t0/tom t may concern.'

Be it known that l, .learns lNGELs, a citizen ofthe United States, residing at Springfield, in the count?,7 of Sangamon and State of Illinois, have invented a new and useful Radiator, of which the following is a. specification.

The invention relates to radiators such as are used in conjunction with gasoline engines, or the like. Such radiators, as hitherto commonly constructed, comprise a large number of permanently attached tubes, usually soldered in the radiator and a large number of radiator. plates, or fins, also soldered in the radiator. The tubes are subject to bursting by freezing, and the tubes and the plates are frequently injured or broken in accidental collisions. By reason of the parts being permanently united, as stated, it is very difficult to repair or replace the broken parts. Only a skilled mechanic can do the work properly and at best the making of repairs and replacements is slow and consequently costly.

Prime purposes of the present invention are to provide a radiator having tubes which may be inserted or removed without disturbing the plates or fins and without disturbing other permanent parts of the structure; and to provide other improved structural details as will hereinafter appear.

With these ends in view the invention consists in the novel features of construction and combinations of parts shown in the annexed drawing, to which reference is hereby made, and which will now be described and recited in the claims.

Figure 1 is a combined front elevation and partial vertical sectional view of a radiator embodying my invention. Fig. 2

' is a horizontal section on the line 2.2. of

Fig. 1 looking downward. Fig. 3 is a greatly enlarged fragmentary vertical section through the radiator on the line 3.3 of Fig. 1 and shows details of one tube and its connections Fig. 4 is an enlarged horizontal section on the line 4.4. of Fig. 1, looking downward, and shows in detail a fragment of one diaphragm. Fig. 5 is a combined elevation and sectional view, showing keepers of modified construction; and Fig. 6 is a transverse section on the line 6.6. of Fig. 5.

The same reference numerals designate the same parts in all the viewsc The radiator comprises an upper water box 5, a lower water box 6, hollow columns 12 intercommunicating between the boxes 5 and 6; upper perforated plates 7, lower perforated plates S, water tubes 9 in communication with the interior of the boxes .5 and 6 through the perforations of the plates 7 and 8, rods 13 connecting the plates 7 and 8, and diaphragms 10, spaced apart from each other and directing the flow of air around the tubes.

The water box 5 is preferably a metal casting, open at its lower end and having a flange 14, extending entirely around the lower part of the box. The box 5 has a tubular neck 15 to admit water to the box and a screw cap 16 closing` the neck.

The water box 6 is preferably a metal casting open at its upper ena and having a flange 17 extending entirely around the upper part of the box.

A flat perforated metal plate 7 is conformed to the contour of the flange 14. A

gasket 25 is between the plate and the flange.I

Bolts 18 extend through the flange and the plate and detachably connect them with each other. The gasket prevents leakage of water between the connected parts.

A at,-perfcrated, metal plate 8 is conformed to the contour of the flange 17. A gasket 26 is between the plate and the flange. Bolts 19 extend through the flange, the gaslret and the plate and detachably connect them with each other. The gasket prevents leakage of water between the connected parts. v

The plate 7 has a series of integral tapered nipples 21, corresponding to the number of tubes 9 in the radiator, and also has openings 20 intercommunicating between the box 5 and the columns 12.

The plate 8 has series of internallyscrew-threaded holes 27 (Figs. 1 and 3,) corresponding to the tubes 9, and also has openings 31 intercommunicating between the columns 12 and the box 8. Tapered nipples 2S screw into the holes 27 and have polygonal heads 29 on which a wrench may be used to rotate the nipples. Lock nuts 30 are screwed on the respective nipples before the'nipples are screwed into the holes, and when the nipples are properly adjusted the nuts will be tightened to lock them in place.'

The box-like columns 12 have fiat ends accurately fitted to the lower face of the plate 7 and the upper face of the plate 8. Screw-threaded rods or bolts 13 firmly unite the parts 7, 12 and 8,V but admit of separating the parts when necessary. The rods .13, in conjunction with the tubular spaces 22 firmly imite the diaphragms- 19 and keep them in proper spaced relation to each other but achnitof separating them when neces* sary.

Each diaphragm has holes 31 (Fig. 4C) accommodating the respective rods 13 and holes 23 accommodating the respective tubes 9. The diaphragms are of very thin sheet brass. The holes v23 may be made by any suitable instrument (not shown) which will perforate the metal just as the tapered end of a pencil will perforate a sheet of paper,

and will form a series of springy fins 24 marginal to the hole. The middle parts of the fins 24; tend slightly towardsthe centre of the hole 23 so that the circumference lbounded by the central parts of the fins is in each instance somewhat less than the outer circumference ofthe tube 9 occupying the hole; it is obvioi's therefore, that when the tube is in place in the hole the fins will be under Vstress and will prevent vibration of the tube inthe hole but will yield to permit insertion or retraction of the tube, as the case may be. 1 prefer to use springy keepers integral with the diaphragm but other suitable keepers may be used without departure from my invention; such, for example, as separate springs 2i (Figs. 5 and 6) attached to the diaphragm 10 and adapted to engage on the periphery of the tube 9 to prevent vibration of the tube and permit easy insertion or'withdrawal of the tube. Keepers of other and different forms will readily occur to persons skilled in the art and need not be detailed here.

To assemble the parts, the rods 13 will be placed in position in the holes 31 of the plater' the box 5 will be connected with the plate by the bolts 18; the successive spacers 22 and diaphragms 10 will be placed on the Yrods 13 and the nuts 32 abutting against the spacers adjacent to the lower ends of the rods will be tightened to hold together the associated diaphragms and spacers; the tubes 9 will be inserted through the holes 23 in the diaphragms in such position that the tapered ends of the nipples 21 will occupy the upper ends of the respective tubes; the screw-threaded nipples 28 will be screwed into the respective holes 27 the columns 12 will be placed in proper position relative to the plates 7 and 8 and the nuts at the lower ends of the rods will be tightened to firmly unite the parts 7. 12, and 8. The nipples 28 will then be adjusted to cause watertight juncture of the ends of the tubes with the upper and lower nipples and the lock. nuts done wit-hout disturbing the other tubes or the diaphragms 10. Y

To replace a broken or damaged diaphragm the intervening diaphragms and spacers will be removed in succession from the rods 13 until the broken or damaged diaphragm is reached; it willVV then be taken out and repaired, or a new diaphragm sub'- stituted; the other diaphragms and spacers will then be'put back in their original order and the plate 8 and the box 6 will again be attached andY secured.

It isA to be noted that the tubes 9 and the columns 12 admit of free circulation of water from one box to the other. It isto be noted Y further that any tube may be detached without disturbing the diaphragme and without disturbing any other tube, and that any diaphragm may be detached without disturbing any tube. Y Y Y i Y i To the best of my knowledge and belief, I am the first to devise and use in a radiator for gasoline engines, or the like, demountable tubes in conjunction with demountable diaphragms; I therefore donot limit my claims to the precise structural details shown or described, inasmuch asrminor modifications may bemade within Vthe scope Vof the appended claims.

Having fully described my invention and the mode of its use, what I- claim as new and desire to secure by Letters Patent is:
